' An objectV o 'ftliis'i 'nventioiiis to provide hay fork which isisoconstructed that it be readily'insertedinto vaquantityiof and when in position may be lockedfso'as toclamp Y or gripari Vexceedingly large quantity of hay.

VAnother objefetfof Ath'S invention is to proA vide a' hay fork having apairoic pivoted tines so that the tine'smay beforced' into'the hay `in a rotary or' drilling movement thereby permitting the forkftd grab a greater Aqu'alntityloi hay thanfis possible v "with the li( y forks', j at i present available.

A further object of this invention isito prof videahay :fork of this .character which may be tripped at aiiyfdesir'ed point so as to release the hay therefrom.

The above and various other objects and advantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being il*- lustrated in the accompanying drawing wherein vFigure 1is adetail sideelevation partly `in E y I l y A yengagement bythe upperend of the link member k'211. soas to limit the i'ocl ing"ii""1'ovc-- ment of the link'mein'ber, and the operating lever- 23 is also provided with :a'stop lug '2G seas to limit'the rockingmovenient 'oi the section of a hay 'ork constructedaccording to the preferred embodiment of this invention; v

Referring to the drawing wherein like iiumerals of reference designate corresponding partsthrougho'ut the several views, the' numeral 10 designates generally a frame which comprises a cross bar-W11 upon the ends-of which are positioned depending tubular members 12, kand an eyelet 13 is swiveled inv the cross bar ll at substantially the center thereof, the eyelet 11 being adaptedto be connected to a cable or rope which lis usedv in lifting thehay for transportation to the desired position. v A horizontal brace 14 is secured to the vertically disposed members 12 at a point spaced downwardly from the'cross bar ll-and' a depending :lug 15k is Vsecured rvto fthe bi Ace nieni-r ber: lflatfa4 point in substantial "alignment with the: eyeletlBQrA ypaii ofitine'si nut 1 8 or 4the like'andlth'e tines 1d ai'efalsoprovided with stolpinei'nbers19iwhich^are ladapted Vto rotatably engagethe" 1lower endH Vportion of the tubular inembersll2so1as to@ prevent longitudinal movement of the 'tines 15 jin the 'tubular members 12.-

When the operating levers23 are'in substantially horizontal position; the lockeelhmbers-eeiwiii be rocked se iiiat'theyso as torelease the hay positioned on the lforkwill be positioned in substantial alignment with the tines 16 and substantially entirely contained within the slot 20 so as not to impede the downward movement of the tines y in the hay.

tines 16, the locking members 22 will be swung l outwardly of the tines lhand atsubstantially right angles thereto so that when the fork is liftedrupwardly, the `hay will -be held on the fork by the locking members The fork may then be rmovedto-the desired point whereupon xthe tripping` cord 28 may be tpulled thereby swinging'th'e operating members 23 into substantially vhorizQntal Vposition Ywhich cooperatively will .swingv the locking Vmembers y22 back into the-slots 2O of the tines and permitting the hay to drop or be yreleased from the fork.

v It will beobvious fromfthe foregoing lthat an exceedingly simple hay forkA has been provided -`by ineansof which the tines may be forced into the hay ina substantially drilling movement whichpermits the tines to be inserted into the hay for a greater distance than is possible where the tines are fixedly secured to the frame as in Amost of the :hay forlrsat present available.
